Wow that's pretty huge sum, it's almost 20btc, you Are a lucky man, I'm pretty sure that you staked high on this bets that's why you had such a huge profit. I've won a huge amount in gambling also but not up to this
That was a huge amount, are you sure of this? no tricks at all? Probably because he wagered a huge amount too that's why the return profit was also big. That is very risky if you roll the dice with 0.05% chances of winning, you should win within after 5-6 losses in a row. But if not, you are totally losing. Well, you are just probably a lucky man. Congrats, I will watch now the video.
EDIT: That was last year. I saw a video right now.
